LYMAN MORGAN, OF PORT WASHINGTON, WISCONSIN.

TRACK-CLEARER.

SPECIFICATION forming part of Letters Patent No. 330,725, dated November 17, 1885.

Application filed January 12, 1885. Serial No. 152,617. (No model.)

To all whom it may concern:

Be it known that I, LYMAN MORGAN, of Port Washington, in the county of Ozaukee and State of Wisconsin, have invented certain new and useful Improvements in Track-Clearers; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it pertains to make and use the same,-reference being had to the accompanying drawings, and to the lettersof reference marked thereon, which form apart of this specification.

The object of my invention is to quickly and effectually remove snow, ice, sand, or similar obstructions from railway-tracks.

It consists, essentially, of a pair of convex rotary disks provided upon their convex faces with wings for cutting andremoving the snow, &c., in front of them, and mounted at the forward end of the supporting-car,and diverging rearwardly from the beak of the plow, of scrolls located about the peripheries of said disks to retain the snow, &c., upon said wings until the same is carried up and discharged through suitable chutes at the sides of the machine.

In the accompanying drawings like letters refer to the same parts in each figure.

Figure 1 is a plan View of my improved machine showing the disks in medial horizontal section on the line as m, Fig. 2. Fig. 2 is a side elevation of the machine with the front side guard removed. Fig. 3 is a plan or top view of the disks and discharging-chutes, the cap-plates of the latter being removed; and Fig. 4 is a rear elevation showing the side guards.

A is the car or frame-work supported upon the wheels K K, or upon ordinary car-trucks.

D D represent the rotary disks, which are mounted in an upright position at the forward end of the car A upon the front ends of the shafts d d, the ends of which are beveled and roll together, so as to mutually brace each other and said disks. These disks D D have convex front faces and are set with their peripheries in planes diverging rearwardly from the beak N of the plow. A horizontal section passing through their axes cuts said disks in a semicircle, as shown in Fig. 1.

a a are wings or scoops having sharp upwork of the machine, separating the disks at their forward approaching edges,and advancing to the front edges of the wings a a at the point of their nearest approach thereto, as shown in Fig. 1.

O O are scrolls forming a continuation of the beak N about the under and rear edges of disks D, where they are made of about the same width as wings a a, the ends of which run closely thereto, as seen in Figs. 1 and 2. By this means the snow, 850., taken up by the wings a a is retained upon the faces of the disks D until it is carried up and discharged at the upper rear quarters of said disks through chutes formed by the scrolls H H, vertical backs I I, and horizontal guards or covers L. The said backs I I form continuations of the beak N, and diverge rearwardly to points on each side even with the outer edges of thewings a a at the outer limits of their travel. The scrolls H H begin at points about the middle of the front edges of disks D D and gradually widen out, forming continuations of the faces of said disks,till they reach the top thereof, where they are gradually brought into a horizontal position, in which they are continued, with their front edges in avertical plane passing through i the edges of the disks till they meet the outer edges of the scrolls O O, which are continued up in a vertical line from the rear edges of the disks, as'seen in Fig. 2, and close the spaces between the forward horizontal edges of said scrolls H H and the curved edges of said disks.

T I arevertical side guards extending back from the rear edges of scrolls O O and chutes H I H I, as shown in Figs.- 1, 3, and 4, and indicated by dotted lines in Fig. 2. They are preferably curved inward at the base,as shown in Fig. 4, and may be extended at the top, if

IOC

desired, so as to envelop the entire car and To prevent the wings a a, when rapidly rotated,- from throwing the snow, &c., over the top of the discharging-chutes, the backs I I may be made higher, or, preferably, horizontal forwardly projecting guards L may be attached to the upper edges of said backs I I, as seen in Fig. 2.

P P arevertical cutters attached to the rear upper corners of the scrolls O O, as seen in Figs. 2 and 3. The inner faces of said cutters are curved, as shown in Fig.3, to throw the snow, &c., in upon the faces of the disks,where it will be caught by the wings a a. The inner faces of disks D are provided with gears G G, formed integral therewith, or separate, as may be most convenient.

F F are gears provided with crank-pins n n, and mounted upon the ends of transverse shaft E, so as to mesh with said gears G G. The gears F F are connected with steam-cylinders O O, by means of crank-pins n a, through piston-rods c 0 and pitmen b b. The cylinders G O are supplied with steam from the boiler B, borne upon the car A.

My improved machine operates as follows: The disks D D being rotated in the direction indicated by the arrows,preferably by means of an independent engine and boilcr,B,mounted upon the same car with the plow, the machine is advanced by a locomotive, or by means of self-contained mechanism, against the obstructing snow, ice, or sand. The wings a a take up the snow, &c., pressing against the faces of the disks D, and retained thereon by the scrolls O O, and carry the same around and up at the front to the top of the said disks, where it is discharged into the chutes formed by scrolls H, I, and L, from which it is cleared by the forward movement of the car and the rotation ofithe wings a a and discharged at the sides of the machine beyond the disks.

I11 clearing away ice or very heavy compact snow the advance of the car must be so regulated as not to stop the rotation of the disks, the wings a a of which gradually cut their way through the obstructing mass about the whole area of the disks.

The mechanism for propelling the plow should be specially constructed for the purpose and be applied to the supporting-car, in order to properly regulate and give a firm, steady advance movement to the plow.

I do not broadly claim the rotary disks provided with radial wings, as they have been heretofore shown and patented.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is.

1. In a railway-track clearer, the combination of the disks D D, provided with wings a a, scrolls O O, and discharging-chutes H I, substantially as and for the purposes set forth.

2. In a railway-track clearer, the combination of the beak N and a pair of convex rotary disks having wings or cutters a a on their convex faces, and set with their peripheries in planes which diverge rearwardly from said beak N, substantially as and for the purposes set forth.

3. In a railway-track clearer, the combination of convex rotary disks D D, having wings aa on their front convex faces, means, substantially as described, for retaining the snow, 850., upon the faces of said disks until the same is carried by said wings to a convenient point of discharge, and means, substantially as described, for receiving the snow, &c., from said disks and discharging the same at the sides of the machine, substantially as and for the'purposes set forth.

4. In a railway-track clearer, the combination of the convex disks D D, having wings a a on their convex faces, gears G G, and gears F F meshing therewith, and mounted upon the ends of shaft E and connected with steam-cylinders O G, substantially as and for the purposes set forth.

5. In a railway-track clearer, the combina-' tion of the convex rotary disks D D, having wings a a secured to their convex faces, beak ,N, scrolls O 0, closing the space between the ends of the wings about the lower portion of said disks, and discharging-chutes composed of scrolls H H and backs I I, diverging from the forward end of the machine rearwardly toward the sides, substantially as and for the purposes set forth.

6. In a railwaytrack clearer, the combination of the convex rotary disks D D, having wings a an attached to their convex faces, retaining-scrolls O O, discharging-chutes H I H I, and cutters P P, substantially as and for the purposes set forth.

7. In a railway-track clearer, the combination of the rotary disks D D, provided with wings a a, and the side guards, T T, substantially as and for the purposes set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

LYMAN MORGAN.
